Rothschild and Stiglitz (1976) show that there need not exist a competitive equilibrium in markets with adverse selection. Building on their framework we demonstrate that externalities between agents - an agent's utility upon accepting a contract depends on the average type attracted by the...

Credence goods markets are characterized by asymmetric information between sellers and consumers that may give rise to inefficiencies, such as under- and overtreatment or market break-down. We study in a large experiment with 936 participants the determinants for efficiency in credence goods...

Using a controlled experiment, we examine the role of nurture in explaining the stylized fact that women shy away from competition. Our subjects (students just under 15 years of age) attend publicly-funded single-sex and coeducational schools. We find robust differences between the competitive...

Using panel data for nearly all service providers in a single industry sector, we examine productivity responses to changes in competition in the United States. The sector offers workplace employee representation through trade union branches which compete with one another for union members whose...

We investigate whether competitive selection processes generate gender inequality in the context of a prestigious graduate fellowship program. All applications are scored remotely by expert reviewers and the highest ranked are invited to an in-person interview. The data show a very large gender...

Environmental policies may have important consequences for firms' competitiveness or profit-ability. However, the empirical literature shows that hardly any statistically significant effects on firms can be detected for the European Union Emissions Trading Scheme (EU ETS). We explain why there...

There has been a recent rapid increase in immigration into Europe, specifically in the form of refugees and asylum seekers. This raises a range of social challenges and a particular focus is education and school systems. A growing body of research investigates the impact of immigrants on native...

We use a controlled experiment widely adopted in the literature to assess the extent of gender differences in attitudes towards competition in a sample of UK professionals working in two different companies. We find no gender differences in attitudes towards competition nor in performance under...

We propose the so-called domestic "embodied unit labor costs" (EULC) at the country-sector level as a new cost-related basis for measures of international competitiveness. EULC take into account that a sector's labor costs constitute only a small share of its total cost which to a large extent...

We compare the performance of high-ability adolescent girls and boys who participated in a a long-running Korean television quiz show. We find there is a gender gap in performance – in favour of boys – across episodes of the quiz show. To investigate underlying mechanisms that might explain...
